No Rick...you can keep yours dirty. But the rest of you really should.

I don't know if you have Roller rockers or not, but just in case you do, it is much more accurate to slide the feeler gauger in from the side to prevent the roller tip from rolling and giving an inaccurate measurement. Something else I've always wondered about is if anybody else here feels that you lose some of solid lifter sound (that &quot;clackity&quot; sound) when you upgrade to aluminum roller rockers. It's always seemed to me that the thick aluminum body of the roller rocker possibly dampens that particular sound. Anybody else ever pick up on this or is it just me?

I think it is a bit quieter Mark. I have rollers and I just feel my way thru and don't go in sideways !

Same deal for me too. But then again, my wife says I'm deaf. [img]<<GRAEMLIN_URL>>/grin.gif[/img]

We argued this exact subject at one of our cruise nights last year.Walt switched to Al.,&amp; when he pulled up,some even thought he switched over to hydraulic.
Definitely a different sound then previous.

I guess I'm just old fashioned, lazy or I just don't want to remember what &quot;sequence&quot; some proven procedure dictates. I just do each cylinder at a time.
I loosen both, then bump it around until the gauge is loose, then I tighten the nut until it's good, then bump it again. If it gets loose again, I tighten it down again. I repeat that until the after the last bump, the feeler gauge won't go in. I know I've covered the base circle that way and the lash isn't too loose or too tight. That's just easier for me then having to remember some IOECOEICOCIC 90deg, 180deg, 360deg ++ -- thing. Once around the block and I'm done and I don't have to remember a thing about &quot;how&quot; I should remember how far to turn it or which valve to run around the car and find or worry about forgetting one.

I do them cold and add .002 to the hot spec. Maybe I should add more on the exhaust then the intake, but that's the way I do it. I really don't think +or- .001&quot; will matter on a fun car.
